The settling of broken rock material to form sediment is known as ...?

• Compaction.

• Sedimentation/Deposition.

• Weathering.

• Erosion.

• Cementation.

Which rock type forms from the cooling and solidification of magma?

• intrusive igneous

• extrusive igneous

• sedimentary

• metamorphic

How do metamorphic rocks form?

• Cooling of Magma

• Heat and / or Pressure

• Cooling of Lava

• Compaction and Cementation

Contact metamorphism...

• changes to rocks over small areas due to pressure from rocks scraping past each other at fault lines

• changes to rocks over a small area near Earth's surface due to heat from magma

• changes to rocks over large areas due to heat and pressure from colliding tectonic plates

The rock cycle describes...

• the continuous movement of water within the Earth and atmosphere.

• the formation, breakdown and reformation of rocks as a result of sedimentary, igneous and metamorphic processes.

• how carbon moves through our Earth's various systems.

• how nitrogen passes from the atmosphere to the soil to the organism and back into the atmosphere.
